Get your seedlings off to a good start with their very own little greenhouse! The bottom 3/4 part of a plastic soda bottle makes for the perfect little dome to cover your little pots with. This would be a fun project to get the kids involved with.
Want to conserve water but still want to make sure you aren't under-watering your garden? Want to establish a simple greenhouse irrigation system? Clay pot irrigation can save 50-70% of water without depriving your plants.
